Is the sex of human determined only by the Father because he has one X chromosome and one Y chromosome?
Women are XX while men are XY therefore, the mother gives the baby an X-chromosome and the father can either give it and X or Y chromosome.
Showing in a Punnet Square:
X X
X XX XX
Y XY XY
The 4 results are the possible combinations the baby can be.
50% Chance Boy and 50% Chance Girl
What else can I help you with?
What is the chance that a human zygote will receive one X and one Y sex chromosome during fertilization 100 percent 25 percent 75 percent 50 percent?
The chance that a human zygote will receive one X and one Y sex chromosome during fertilization is 50 percent. This is because an individual inherits one sex chromosome from each parent, with the father contributing either an X or a Y chromosome, and the mother contributing an X chromosome.
What are the name of 23 chromosomes in human body?
No, there are 46 chromosomes in one cell. A gamete, or sex cell, has 23 chromosomes because during fertilization, the female and male gametes (egg and sperm, respectively) come together to form a new cell with 46 chromosomes
What is the chance that a human zygote will receive one x and one y sex chromosomes during fertilization?
The chance is 50%.
The human chromosome apparently lacking in gene influence is the?
Y chromosome is the human chromosome that is apparently lacking in gene influence. It is significantly smaller than the X chromosome and carries fewer genes, mostly related to male reproductive functions.
What portion of the human Y chromosome is homologous to the human X chromosome?
The pseudoautosomal regions (PARs) at the tips of the Y chromosome are homologous to regions on the X chromosome. These PARs are responsible for pairing and recombination between the X and Y chromosomes during meiosis. About 5% of the Y chromosome is homologous to the X chromosome in humans.
Is the sex of a human offspring determined by the mother fathe r or neither?
Technically, the sex is determined by the father. The egg is always an x chromosome. The sperm can be either an x or a y chromosome. An xx makes a female, and an xy makes a male.
How the sex of a person determined?
Human cells contain 23 pairs of chromosomes for a total of 46. There are 22 pairs of autosomes and one pair of sex chromosomes. The sex chromosomes are the X chromosome and the Y chromosome. If you are male you have the XY chromosome.. making you a male. If you are female you have the XX chromosome.. making you a female. It all depends on the father, if the father gives an X chromosome... you have a girl. Because it combines with the mother's X chromosome.. creating XX(a female) If the father give a Y chromosome.. you a have a boy. It combines with the mothers X chromosomes.. creating XY(a male)

What percentage of human offspring receive a Y chromosome from their father?
Approximately 50% of human offspring receive a Y chromosome from their father. This results in the development of male offspring with a typical genetic makeup of XY.
How many sex chromosomes does your mother give to a normal baby........and father?
The mother and father both give a normal baby 23 chromosomes. This is because, a normal human has 46 chromosomes in all cells, except sex cells. So, a human receives half from the mother and half from the father thus 23 from each.
What determines the sex of a human?
Whether they have 2 X chromosomes= girl, of one X chromosome and one Y chromosome= boy
Which chromosome determines a human s sex?
The sex of a human is determined by the presence of two sex chromosomes. Typically, males have one X and one Y chromosome (XY), while females have two X chromosomes (XX). The presence of the Y chromosome determines male development.
The male human is represented by sex chromosome of what?
The male human is represented by a sex chromosome consisting of one X chromosome and one Y chromosome (XY).
What is the chance that a human zygote will receive one X and one Y sex chromosome during fertilization 100 percent 25 percent 75 percent 50 percent?
The chance that a human zygote will receive one X and one Y sex chromosome during fertilization is 50 percent. This is because an individual inherits one sex chromosome from each parent, with the father contributing either an X or a Y chromosome, and the mother contributing an X chromosome.
Where do human males get their x chrosome?
When a person is born they get one chromosome from the mom and one from the dad. A female has XX chromosomes a male has XY Cromosomes. So a male would get the Y from the dad and the X from the mom.
List these in order from smallest to largest chromosome gene cell?
Smallest to largest: Gene (a place on a chromosome); chromosome (there are 46 in human cells); and DNA (because it accounts for all the genetic material in a cell).
What chromosome determine human blood group?
The ABO blood group system is determined by the ABO gene located on chromosome 9. This gene determines the presence of A and B antigens on the surface of red blood cells, which in turn determines a person's blood type (A, B, AB, or O).
